Oh sweet! I somehow missed it on the announcement. I only saw Mail, Calendar, and Contacts.
My current employer uses Office365. It is laughably inferior to Google Apps. Unless you are a child of the 80s and grew up drinking Microsoft Exchange Kool Aid, there is absolutely no good reason to use Office 365 over Google Apps.
I've never been much of a Microsoft fan but I personally pay for a business Office365 Exchange account just for my personal email. I'm sure there's reasons to prefer in either direction but for me I don't have any complaints and it all works great.
I am user of both Google Apps and Offie365 and my experience so far has been opposite. At least, Google Apps' web based UI is inferior to Office desktop version. SharePoint for team collaboration to me is a much better experience. Could you list few things where Google Apps beats office 365. I occasionally consider the switch and did not find GoogleApps to be better.
If you ever have to do advanced formatting in word/ppt or crazy in depth excel functions office still wins.
